Straight stroke electric actuator HLL

product overview

The HLL series electric actuator is one of the actuator unit products in the DDZ series of electric unit combination instruments. The actuator and the regulating valve body form an electric regulating valve, which is the actuator regulating mechanism in industrial process measurement and control systems. It can be widely applied in various industries such as petroleum, chemical, water treatment, shipbuilding, papermaking, power plants, heating, building automation, and light industry. It is driven by a 220V AC power supply and controlled by a 4-20mA current signal or a 0-10V DC voltage signal. It can move the valve to the desired position and achieve automatic control, with a maximum output torque of 25000N.

Performance characteristics

Multiple work configuration options, flexible and convenient;

Control signal: current signal (4-20mA or other non-standard signal)

Voltage signal (0-10V or other non-standard signals)

Positive and negative effects can be selected, making it easy to achieve split range control mode.

Output signal: current signal (4-20mA or other non-standard signal)

Voltage signal (0-10V or other non-standard signals)

Valve action direction: positive and negative action selection;

Self adjustment of stroke: Innovative mechanical design, easy and fast adjustment of stroke position, adaptive adjustment of input signal and stroke relationship, meeting the needs of valves with different strokes;

Self diagnostic function: The actuator automatically records working parameters during operation. When the actuator malfunctions, the main control module promptly detects and alarms, and the fault is displayed by LED lights;

The control circuit is more reliable: the motor drive adopts contactless control, no sparks, and has a long service life; The circuit module is fully digital controlled, without the presence of mechanical potentiometers, so users do not have to worry about the impact of mechanical vibration and transportation on product accuracy; Adopting advanced anti-interference technology, it can handle even harsh environments with ease, and the new "watchdog" technology keeps away from the troubles of "crashes";

Reverse direction of actuator movement delay protection, longer lifespan of power transmission components;

Lower work noise.
